Caleb has had a milk allergy and has been getting bm bottles mixed with RTF alimentum for months now. He refuses the powdered alimentum because it smells TERRIBLE and will no longer nurse. I am trying really hard to keep pumping, but my supply is slowing starting to dwindle. He is no longer bothered by soy (if ever) as I consume soy products often. DH and I will certainly do whatever to feed C, but because he is on alimentum, and only takes the RTF (I've tried the powder over and over again) it is going to be unbelieveably expensive to go straight to formula as the RTF is $9 per quart (32 oz.) which is basically a day supply of formula. I asked about switching to soy, but our pedi doesn't really like soy formula. Do you think I should try to slowly introduce regular formula? Like a 1/4 oz mixed with a bottle once/day? His original side effects from milk were mostly fussiness and mucousy poop with visible blood in 2 diapers when he was 3 weeks old. He hasn't had milk protein since then. TIA!
